The production of chemical enterprises is characterized by high temperature, high pressure, flammable and explosive, and strong continuity.
Inspection is always the first important task.
What does inspection rely on?Meticulous. Inspection is not only in the patrol, but also in the inspection. Inspection is not a simple circle, a point inspection, hang a card on the handover, the key is to check hidden dangers, eliminate risks. The number of equipment is large, the types are large, the operation task is heavy, the leakage occurs from time to time, and various security risks are coming. This requires that in the inspection work to be comprehensive, there can be no sloppy. Check carefully, compare before and after, understand the dynamics, and eliminate hidden dangers in time.
Why need inspection
Inspection can detect device anomalies in time to prevent system shutdown and accidents. In actual production, due to the difference in industry and process, but the general requirement should be: can find the abnormal situation in the production site, and can be handled simply. This includes equipment, pipes, meters, control points, etc. The purpose is to ensure the stable operation of production.
How to do inspection work well
1.The system of itinerant inspection of production equipment shall be established, and corresponding records shall be perfected and established
2.In the inspection process, the personnel on duty should achieve five positions, that is, "listening, touching, checking, seeing and smelling".
3.Pipelines, equipment, valves and other equipment in the operation of the running, bubbled, dripping,leakage in the inspection process to find a corresponding solution, and make a record.
4.In the process of equipment inspection, inspection personnel in strict accordance with the safety procedures, with a high sense of responsibility and "look, smell, ask, cut" inspection method, can find and eliminate accident hazards in time.
The most important thing is to remember the four inspection methods of "look, smell, ask and cut"
The four inspection methods of "look, smell, ask, and cut" are to comprehensively monitor the shape, position, color, smell, sound, temperature, vibration and other aspects of the operating equipment through the functions of the inspectors' eyes, nose, ears, mouth and hands, and find abnormal phenomena and make correct judgments from the changes in the above aspects.
01 Look, Keep your eyes on the eight paths
When inspecting equipment, inspectors should keep their eyes on the eight paths, make full use of their eyes, from the appearance of the equipment to find running, bubbled, dripping, leakage, through the location of the equipment and even parts, color changes, to find whether the equipment is in normal condition, discover in time and kill the accident signs.
02 Smell,Keep your ears can be heard everywhere
Inspection personnel should their ears can be heard everywhere, make full use of their nose and ears, find the smell changes of the equipment, whether the sound is abnormal, so as to find out the abnormal state of the equipment, and conduct targeted treatment.
03 Ask, Ask more about work
In the process of shift handover, inspection personnel should ask more questions, especially for the work of the previous shift and the work that has not been completed, to ask clearly, to understand in detail, to know well, to prevent accidents from occurring in the interval of shift handover.
04 Cut,Be more hands-on
As long as the equipment can be touched by hand or through a special inspection tool, the inspection personnel should feel the temperature change and vibration during the operation of the equipment by hand or special tools; Before operating the equipment, the operation actions and procedures should be simulated empty-handed. Do not touch carelessly, causing misoperation.
Risk control of inspection
①Keep an eye on the new,new staffs,new machines, new crafts ,new products,New materials.
②Increase the frequency of key stations and strictly control the general station according to the normal frequency, one can not be less.
③As a key monitoring of the whole inspection station, the problem of the whole inspection station can be traced back to the specific work post, traced back to the source, and controlled is the method of getting twice the result with half the effort.
④Regular sampling of the products according to the sampling plan, easy to find even the full inspection can not find the problem. It is the best way to effectively cross control sampling risk.
⑤When problems are found, the next process must be notified in time, so that the next process can assist in defense and check, and the next process should be informed of temporary changes in time.
Key inspection
Key equipment inspection; Key inspection of equipment with equipment defects; Key inspection of equipment operating with disease but not treated; Focus on inspecting the equipment to be repaired. Different devices, inspection focus is also different.
There are mainly three aspects: one is to see, two is to hear, and three is to touch.
Look, mainly for static devices.It is to see the on-site temperature meter, pressure gauge, liquid level meter and other instructions consistent with the room, pay attention to whether there is leakage.
Listen, mainly for mobile devices. There's no noise, sharp friction, excessive vibration.
Touch, temperature is not over temperature, etc.
